Application filed January 24-1907- Serial No. 353.776-

To (Illa/17mm it may concern:

Be 1t known that l,'VV1LBURN N. DENNI- and has a diametergreater than the smaller soN, a citizen of the United States, and a resi- 1 diameter of the aperture in the support so as dent oi the borough of .\'lerchantville. county of Camden, andState of New Jersey. have invented certain new and useful Improvements in Tilting 'lurn-Tables for Sound Recording and Reproducing .\lachines, of which the following is a full, complete, and exact disclosure.

One object of this invention is to provide a mounting for a turn-table used with the disk type'of sound recording and reproducing niatilted' out of its normal osition upon its drivringing any undue stress upon the spindle to bend it.

Further objects of my invention are to su portthe turn-table independently of the splndle'by which it is rotated, without having any relative motion between the said parts; to render this portion of the mechanism of a talking machine absolutely noiseless ularly pointed out in the claims and illus- 'trated in the accompanying drawings, in

which Figure 1 is a central vertical section of adevice constructed in accordance with this invention; Fig. 2 is a perspective view of a detail of the device; Fig. 3 is a vertical section of the device showing the turn-table in a tilted position; Fig. 4 is an elevation, partly in section of a central fragmentof the device; and Fig. 5 is a bottom view of Fig. 4'.

Referring to the drawings, the spindle 1 drives the turn-table or record support 2 which is rotatably' mounted as usual in the frame 3 of the nnichinc and is actuated by any suitable means. The record support 2 is prbvided with :1 rent rul aperture 4 and with a downwardly extending hub 5, provided with oppositely d isposed radial slots 6 in the lower edge thereof. The said aperture 4 converges inwardly from hot h sides of the support. The said shaft 1 is provided with a reduced upper end 7 which is threaded to receive a nut 8. The nut 8 is in the form of an elongated cylinder having a screw slot'at its upper end. and, a llange at its lower end which bears against upon the, record support.

tends through the shaft and projects laterally therefrom and engages in the said slots 6 of the record support to form a means of rotating sand support. The lower face of the end of the aperture in the record support,-

The nut also furnishes record support 2 is provided n'zith'a down-' with the support. Rigidly secured to. the shaft 1 below the record support is the disk 11, which is provided with an upwardly facing circular bearing 12 engaging against the said tracks of the record support to carry the same. The upper surface ofthe disk 11 is provided with a central recess 13 into which extends the said hub of the record support. With thisconstruction in'mind it is evident that the record support 2, when tilted upon its bearing, slides longitudinally upon its driving shaft, and the shape of the central aperture of the record support is such that no lateral pressure is brought to bear upon the driving shaft to bend it.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States, is:

1. In a. sound recording and reproducing machine, a record su port, means for rotating the same, and a earing for said record support rotated b said means, said record support being free y tiltable away from and towards said bearing.

2. In a sound recording and reproducing machine, a record support, means for rotating the same, a bearing for said support rotated b said means, said record support being free y movable away from and towards.

In a sound recording and reproducing record support provided with a bearing surface and a central aperture, a driving'spindle therefor extending through said aperture, a diskrigidlyifixed upon said spindle and having an upwardlvfacing cirfor said track, said record support being freely tiltable towards and away from said-bearing.

8. In a sound recording and reproducing machine, a record support provided wi h a downwardly facing bearing surface, a downwardly extending hub provided with a central aperture, a driving spindle therefor extending'through said aperture, and a disk upon said spindle and having an upwardly facing bearing and a central recess in its upper face, said record support being freely tiltable towards and away-from said bearing. l
